Thanks Olmy. I have tried disabling the firewall (firewalld service) and it makes no difference. I then re-enabled it, and started IPTABLES and the output is below. I am not familiar with static firewall, and reluctant to go there, as this was working seamlessly in a prior install. You can see from the journalctl file that IPTABLES starts up and then almost immediately stops.'
As I asked before, is this normal behavior, to immediately stop IPTABLES after loading it, that they are only loaded once at startup, and then exit?
If it is normal,as I believe it is, then firewall and IPTABLES seems not to be the problem, and I am still seeking guidance:
-- Unit firewalld.service has finished starting up.
